The basic problem is that one needs a number of bits (at least 16) for normalization, which limits the time range one can work with. This means that 32 bit leaves only room for 1 millisecond resolution, the remainder could maybe saved and reused later. So AFAICT using micro- or nanosecond resolution doesn't make much computational difference. bye, Roman - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
